CONNECTING-BRACKET FOR CYCLE OR LIKE FRAMES.

SPECIFICATION forming part Of Letters Patent No. 636,698, dated November7, 1899.

A li tion fil d March 29,1898. Serial No. 675,595- (No model.)

To ctZZ whom it may concern:

Be it known that I, EDUARD ScHiiRHoFF, a subject of the Emperor ofGermany, and a resident of Magdeburg-Buckau, in the Kingdom of Prussiaand Empire of Germany, have invented a new and useful form ofConnecting-Bracket for Tubular Members of Cycle- Frames or the Like, ofwhich the following is a specification.

The object of the invention is to provide a strong, durable, andeffective joint in which all brazing of the parts shall be dispensedwith, thus rendering the assembling of the parts easier and doing awaywith the disadvantages arising from heating the parts.

The invention is illustrated in the accompanying drawing, in which thejoint is shown in section.

In the drawing, 0. represents the socketpiece, to the member or arm 0 ofwhich the tube b is to be connected. The portion 0 is provided with agroove 6 in its inner face, in which is sprung a ring of suitable springmaterial, which is placed upon the tube 19 at a suitable distance fromits end before the tube is inserted. The socket also has a recessedportion f. The tube b is then forced into the socket, the ring (1springing into the groove, and a suitable expanding mandrel isintroducedthrough an opening Z in the socket-piece, and the end of the tube isexpanded out to the diameter of the recessed portion f of the socket. Aplug g is then placed in the expanded end of the tube, after which theopening Z may be closed in any suitable manner.

Having thus described my invention, what I claim is In a joint forcycle-tubes, the combination of the socket 6 having an annular groove 6'and inner recess f in its inner face, the springring located in saidgroove, the tube extending into the recess through the ring and having areduced portion corresponding to the ring, the end of the tube beyondthe ring being expanded to fit the recess f and the plug 9 in theexpanded end of said tube, substantially as described.

In Witness whereof I have hereunto set my hand in presence of twowitnesses.

EDUARD SGHURHOFF.
